IMPROVEMENT IN SLATE-FRAMES.

' Speeication forming part of Letters Patent No. 144,104, dated October28, 1STE.; applicationl led June 25, 1873.

To all whom it may concern:

Beit known that I, ALBERT H. J ocELYN, of the city, county, and State ofNew York, have invented an i Improvement in Slate- Frames, of which thefollowing is a specication:

This invention relates to slates for marking or Writing purposes, inwhich frames are used to bind and hold the slates proper Within them 5and consists generally ina novel construction fot' the frame, wherebythe slates may be slipped to their places, and lremoved when necessaryto renenr them, by sliding them in or out of slots in the end or side ofthe frame, subject to support at their backs when inserted by adiaphragm connected with the frame, and ot' retention Within the latter.The same construction applies toa single sla-te.

In the accompanying drawing, which forms part of this specification,Figure l represents a face vieiv of a framed slate constructed inaccordance with ,my invention; Fig. 2, a sectionof the sameon thelinexx;Fig. 3,21, section thereof on the line y y; and Fig. 4, a View inperspective of one ot' the angles or corners of the frame.

Similar letters of reference indicate corresponding parts.

A A and B B represent the side and end pieces of the frame, which arehere shown as made double to receive two slates, C C, down within themthrough slots I) I) in. the one end or side of the frame, Which latteris suitably constructed for the purpose-that is, either by recessing theinterior faces ot' the pieces composing t-he frame or by introducingextra pieces c c between said frame pieces-and a diaphragm, D, extendingacross the frame and forming a support or back to the slate or slates CC, said diaphragm extending either Wholly or partially into the edgesot' the frame, and being secured by the same means, Whether pegs, brads,or glue, which hold the side and end pieces of the frame together, andvirtually forming a binder to hold the several pieces of the frametogether, as Well as to form a support to the back of the slate orslates. This diaphragm D may be ofpasteboard, Wood, or any suitablematerial, and the slates C C may either be of natural stone or of anyartiiicial composition. I prefer to use what is known as the silicateslate.

For school and other purposes a slate thus constructed will be foundVmost useful and economical., inasmuch as the frame braced by thediaphragm D Will answer for almost any number of slates proper,introduced, as wear requires, through the slots I) b, or either of them,accordingly as the slate is a single or double one.

The slates C C, or either of them, when in their places, may be securedfrom slipping or sliding out through the slots b b by various means 5but a simple and efficient device for the purpose consists in a cross,plain, or eyeleted hole, d, through the portion of the frame in whichare the slots b I), outside of the edges ofthe slates When in theirplaces, and so that a string passed through said hole d will serve as astop to the slates proper as Well as, it desired, a means of suspendingthe slate or of attaching the pencil.

If desired, instead of ina-king the frame of the slate as described, thesame may be struck up, or molded in halves or sections out ofpcqiier-mach or other material, with provision for the slot or slots bto receive the slate or slates, such halves or sections being' securedAtogether by any suitable means.

W'hat is here claimed, and desired to be sccured by Letters Patent, ish

l. The combination of the diaphragm D 'with the side and end pieces A Aand B B of the frame, and the slot or slots b for the removable slate orslates, said diaphragm servl ing to brace the frame pieces together, andto form a back or support to the slate or slates, essentiallyl as hereindescribed.

2. The combination, with the slot or slots I; in the frame, of thecross-hole d and the slate or slates G, substantially as and for thepurpose herein set forth.
